Some aspects of forging modeling

Abstract

This paper written in part with a European perspective describes recent research by the author and co-workers in the area of metalforming processes and highlights some areas for future research. Forging simulation is initially discussed against a background of the commercial case for its use. From early research developing the Upper Bound Elemental Technique (UBET) methods of designing preforms are discussed that include a reverse simulation technique based on a Tetrahedral Elemental Upper Bound Analysis (TEUBA). Interface properties can be quite critical in metalforming but yet the data that is integrated with commercial simulation software is not quality assured. Some research on modeling of friction and heat transfer to overcome this problem is described.
